Configuring Site-to-Site IPsec Application IKE
At a aerial level, the IPsec agreement action on the Cisco PIX firewall consists
of three above steps:
1. Planning Deciding on the capacity of IPsec behavior used, such as the SA
establishment adjustment (if IKE is acclimated or SAs are configured manually),
IKE parameters, including the associate affidavit methods (using preshared
keys or agenda certificates), the protocols that will be acclimated (ESP
amdpr AH) and in which modes, and the encryption algorithms.This
step additionally includes ensuring that the aeon are able to communicate
without IPsec and that all IPsec packets are accustomed to bypass ordinary
access lists and conduits.
2. Configuring IKE (if used) This footfall includes enabling IKE on the
firewall, configuring action ambit for Phases 1 and 2, and defining
the affidavit adjustment (pre-shared keys or CA).
3. Configuring IPsec ambit This footfall includes defining interesting
traffic, configuring transform sets, creating a crypto map, and applying
this map to an interface.
Using an example, let’s go through the agreement of a site-to-site IPsec
VPN application IKE.We additionally altercate the differences amid application pre-shared keys
and agenda certificates.
